A nuclear bomb is not a dirty bomb

A dirty bomb attack is a ‘real threat’ faced by Britain, the Foreign Office will warn today. The government claims nuclear terrorism is still one of the biggest threats to global peace. Minister Alistair Burt will use a speech to warn of the dangers posed by a rise nuclear weapons being smuggled around the world.

hmmm well if you’re planning to pack yer dirty bomb with light weight commercial grade stuff then yea not much of a threat.
.
But if you got something a little more potent then it could kill a serious amount of people. and cause absolute havoc.
.
one with a good sized dose could easily make the tube unusable for quite some time, as well as exposing many. (is the paranoia part of your brain asking why all British transport police in london carry radiation detectors yet?)
.
And this is of course before you get to devices that come transit van size.
.
As for actual nuclear bombs, Well for a start the USA have already lost about 3, and Russia have a few unaccounted too.
.
Iran is also fairly sensible, they wouldn’t actually use a nuke even if they had one (for the M.A.D. reasons tim mentioned)
.
If you wanna worry, worry about the syrian stuff. you know how for the first time in History we have a country with powerful 2nd gen bio and chamical nerve agent wmd’s in a state of civil war.
.
Hundreds of tonnes of the stuff…and it only takes a a few drops of the good stuf to cause utter devastation.
